Peel prawns down to the tail fin. Cut into the back and remove the black gut. Rinse shrimps cold and dab dry. Heat the oil in a pot or deep fryer to approx. 170 °C.
Whisk the egg white with 1⁄2 teaspoon salt. Mix Panko and grated coconut. Turn the prawns first in the egg white and then in the panko-coconut mixture. Press the breadcrumbs gently. Fry in hot oil for approx. 3 minutes until crispy.
Drain on kitchen paper. Put 1 skewer into each shrimp and arrange with e.g. mango salsa.
